Since there is a resize option in Piskel that just resizes the canvas. But I want a resize object option! This would be useful so people don’t have to recreate their objects but bigger.
I think there is some misunderstanding or i don’t get what you are seeking ?
Piskel is not directly related to object size, and there is already a Scale action in Sprites.
Keep in mind Piskel is not actually part of the engine (it is a completely separate tool and open source project, just bundled in the engine as a way to assist. It’s not the only/primary way to create assets, or anything) and therefore the devs cannot complete feature requests for it.
As mentioned above by infokubarcade, you can resize your objects on the fly via events, or by clicking “Custom size” on an instance in the scene editor and dragging it as you need.
As this is a feature request for Piskel rather than GDevelop, I’m going to go ahead and close this out, but I hope the above helps!
